Missing data after Bariatric surgery

What this data shows:

Data completion is an important part of quality control of national audits.

How the data is gathered:

The NBSR uses a minimum dataset for the initial patient record.  If one or more of the data fields are not completed the record will be flagged as incomplete.  The data completion records are expressed as funnel plots and individual surgeons who have data completion rates outlying the 99% and 99.9% confidence limits are flagged.

When the data is shown:

Different hospitals and bariatric units will have varying ways of recording data.  It is recommended and expected by HQIP that administrative support be put in place to enable accurate data entry and completion of all the initial patient records covering patient operations.Data collection is just one part of a process of care, and surgery itself is just one aspect of a multi-disciplinary team process of care that involves a wide range of healthcare professionals dedicated to the care of patients with severe and complex obesity. These include dieticians, specialist nurses, psychologists, bariatric physicians, anaesthetists, theatre teams and recovery staff, ward nurses including high dependency and intensive care nurses, out patient staff, radiographers, radiologists and exercise therapists. The close working and performance of the whole MDT is integral to the overall outcome.

More information about the data source:

Data are only available for those surgeons who are members of the British Obesity and Metabolic Surgery Society (BOMSS), and who submitted data to the audit over the relevant time period. Data are self-reported, or entered by delegates of individual surgeons, and have not been independently verified against other data sources.Individual surgeon volume must also be interpreted with caution since units may only start surgery part way through an analysis period or a surgeon may stop operating if they retire or a service is moved elsewhere as part of NHS service changes. Surgeons may also operate on NHS patients in 2 or more hospitals so that one unit’s activity may not reflect the overall workload of an individual, nor take into account the surgeon’s volume of work in non-NHS sectors.

Data Source:

The data are taken from UK National Bariatric Surgery Registry, operated by BOMSS and Dendrite Clinical Systems Ltd.

Data Period:

Cases operated upon between 1st April 2013 and 31st March 2016 inclusive
